Generally, reels constr-ucted on ,the principle s l sed i e Kn eseh Patet 2,219 914, h been ,a tee ees y. m nted in th p i manufacture offilamentary ,rnaterial such as rayon yarn, thread, etc. The reelscomprise two e e ts r atin on a e efi et' an va e to each other andwhich cooper t to advance thread-in a helical manner. Such .twosjelementreels, usually, have been adapted for the performance of a singleprocessing step, Because of their adaptability ir'ra .continudus processit would be advantageous to perform a plurality of processing steps onthem.

A reel has been proposed by the Loye tt Patent 2,167,662 which permitsthe performance of more than one thread processing step. The patentdiscloses a reelhaving :at least two eccentriolfiel member sections'inlieu of one continuous eccentric reel member. The one reel member .wasreplaced by the two to lengthen the reel and to overcome possible barinterference between adjacent bar members which would result if the barmembers of such'an eccentric reel member would exceed a 'lengthbeingdependent upon the amount of askewness, the spacing between the barmembers, and the numberof bar members used. Lovetts solution to oyercomebar member interference wasr to position the eccentric reel me bers inthe same .direet en. and nclin n each about the same amount, generallyin the same plane. 7

While such a stepped or substantially sawtooth positioning of theeccentric reel rnembers advances thread over the reel, thethread-'helix-is s me at di o ed u e b met ens erre from one reel membersection toanother. {The distortion of the helix tends to 'impair' t-he-quality of the thread as well as to reduce, to an extent,

the efiectiveness of certaintreatments because of a ehangein the pitchof theturns of thread.

Figu e .11 ast matic .iiesr zn. 11ewiie1th periphery of the concentricreel member ID. The

bar members 13 extend unbrokenly for their en-- tire length endingdesirably in a supporting ring 14 at one end and in a flange I at theother end. The supporting ring M is concentrically mounted on a shaft 15to which it is fixed by means of a set screw 17 which is threaded in ahub portion [8 that forms an extension of the supporting ring 14.Desirably the flange 15 is secured by a plurality of screws 28 to acircular relation to form separate reel members ll, l2

respectively. The combined lengths of the bars 23 and 24 aresubstantially equal to the length of the bars l3 of reel member if].Each set of bar members 23, 24 is supported on a hub that is adapted torotate about an axis that is offset and askew to the axis of theconcentric reel member [0. Advantageously, bar members 23, 2t rotateabout axes that are arranged about the axis of the concentric reelmember In in an end-to-end relation and at askew angles thereto so thatthey intersect. The eccentrically positioned axes are offset and eachlies in a separate plane that is parallel to the axis of the reel shaftand arranged in consecutive order about the reel shaft axis. As shown,bar members 23 are supported by the hub 26 which is rotatably mounted ona sleeve bearing 21 that is positioned about the eccentric 28 carried bya longitudinal bearing sleeve 31] in which rotates the shaft l5. ,Bars24 are likewise supported by a hub 32 that rotates about a sleevebearing 33 mounted on an eccentric 34 also on the sleeve 36. Theeccentrics 28' and 3d are offset and askew to the shaft 16. The hubs 26and 32 are fixed against lateral displacement .by an end retaining meanssuch as a washer 3B and a retaining ring 31.

The eccentrics 28 and 34 :as hereinbefore mentioned are fixed to thesleeve through which rotates the shaft l6. Sleeve 38 extends through thereel supporting .sleeve 40'. The reel support has a flared section 4|that is adapted to fit V ner end of the support also is serrated as wellas both ends of the eccentric 34, both ends of a spacer 45, and one endof the eccentric 28. The serrations not only prevent rotation of theeccentrics when theirposition has been determined but they also permitavery fine adjustment of them.

The eccentric reel member assembly 'is kept.

from lateral displacement by a collar 4'5 which abuts against theeccentric 28. The collar has threaded through it a set screw 41 whichbears against the reel shaft it. The concentric member is held inposition at one end by a shoulder 49 on the support 40 and at the otherend by the 'set screw H in the hub I8. The support 48 itself abuts aflange 58 on sleeve 30 which in turn abuts an annular ring 5| on theshaft [6.

Further, the reel shaft I6 extends beyond the flanged portion 4| of thesupport 40. There is mounted at substantially the end of the shaft IS adriving gear 52. The driving gear 52 in turn incorporates a slip-clutch53. The clutch 53 comprises a plurality of spring backed balls 55 whichare set in recesses provided for them in the annular wall 56 of the gear52. Springs 51 are seated in radial holes 58 provided for them in asleeve 59 which is fixed to the shaft 16 by means of a set screw 60. Asa result of the clutch, any overload on the reel will not damage thedevice but will make the gear 52 slip about the sleeve 59.

There is schematically shown in Figure 5 the advantageous arrangement ofthe axes of the eccentrically rotating reel members. The line A-Arepresents the axis of the concentric member [5 while the lines B--B andB'B represent the axesofthe eccentric reel members l2 and Hrespectively. The lines BB, B'-B' are inclined so that they intersect ata point BB. This point when radially extended is equivalent to thetransie tion points in the tapered sections of the bar members. Becauseof being tapered the bars have substantially similar transition pointsand the thread readily passes from the one eccentric set of bar membersto another.

The ends can be desirably tapered or arranged as shown in Figure 6 sothat the transition point of each pair oftapered ends is the same andall points-lie in about the same vertical plane. The inclination of theaxes as shown in Figure 5 is exaggerated in order to emphasize theiradvantageous arrangement. Actually the inclination is of a very smalldegree, being only great enough to give the desired rate of travel and aminimum of thread helix distortion over the transition points.

The invention has been described with reference to a two-stage reelalthough, obviously. the construction lends itself to a reel having asmany stages as desired. This can be readily seen from Figure 5 wherethere is shown an additional axis B!I BI" V I claim:
